When i started WFP i didnt want hassle of carrying roof racks etc around, we now commute about 85 miles per day, mainly high speed/motorway. I bought one of those collapsable ladders that can also double as a step ladder, which is short enough to fit in our VW caddy with ease, but which is tall enough to get me up onto first floor flat roof extensions, etc. On short gates I can set it as a step ladder and get over that way, and you just walk up and over quite simply, but im not sure if it would quite fit over a full size gate. I can get to the first floor window but dont normally have to. They do feel a bit shaky tho, nothing gives you confidence like a proper full size ladder under you, I am 6 foot 1 tall and , erm, 16 stone, or just over if had a good breakfast, and it is still going "strong" after nearly 2 years. And not heavy or bulky to lug about either.
